Each year we survey the Cobalt Core, our pentester community, to hear who they enjoyed working with the most. We like to do this to gain insights on who our community values working with and why.
We describe our community as a group of exclusive pentesters with exceptional skills in collaboration, teamwork, technical expertise, and professionalism. What we end up finding out through end-of-the-year surveys, like this one, is that our pentesters share the same values in their Core colleagues. When someone notes why they enjoyed working with another pentester it always comes down to three key qualities: collaboration, technical skills, and overall positive community impact.
Meet the pentesters who were nominated by their peers for possessing these traits and more:
